JOHN E. SCOTT, OF PHILADELPHIA, PENNSYLVANA, ASSIGNOR OF ONE-HALF TO ROBERT L. RUSSELL, OF SAME PLACE.

ICE-CREEPER.

SPECIFICATION forming part of Letters Patent No. 502,324, dated August 1, 1893.

Application filed February 2, 1893.

To a/ZZ whom it may concern,.-

Be it known that l, JOHN E. SCOTT, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State 5 of Pennsylvania, have invented a new and usefullmprovement in Ice-Creepers, of which the following is a specification. i

The invention consists of a supplemental, or inclosing heel for a boot, or shoe, constructro ed of a piece of india-rubber, or rubber coated fabric, so shaped within itsinner surfaces, as to conform to the curvatures of the outer surfaces of the heel, and provided with an upwardly projecting flange that extends at a I 5 slight angle rearward laterally across the front y surface of the heel. This upright ange being inclined slightly to the rearward, causes by contact with the straight forward surface of the heel, resistance sufficiently great to 2o bind the creeper tightly and rigidly hold it in position upon the heel of the boot, without the aid of confining clamps,or screws,as willbe more clearly understood from the following description, and accompanying drawings mak- Figure l, isa side elevation of my improved Creeper. F ig. 2, is a vertical section of the same. Fig.4 3, is a plan view. Fig. 4, is a front elevation, viewed in the direction of the ar- 3o row R, see Fig. l.

Like letters of reference in all the figures indicate the same parts.

A, is the improved creeper, which has the rear portion Z), extended at a slight angle Serial No. 480,808. (No model.)

outward vertically, and of curved form cir- 35 cumferentially, so as to surrou nd and conform to the outer surface of the curvature of the heel of a boot, and of sufficient height to secure a firm retaining hold thereon.

C, is a ange, forming part of the heel, ex- 4o tending upward from the sole of the Creeper, and at a slight angle rearward laterally to the main portion A, in such a manner as to draw the rear portion b, forward, by reason of the resistance of the straight forward surface of 45 the heel against the inclined inner surface of said flange C, thus retaining the creeper in position.

The outer surface d, of the sole of the Creeper is formed into inverted pyramidal points, to 5o clutch onto icy places.

I claim as my invention-- The herein described creeper, consisting of the integral elastic casing, conforming to the contour of the heel, and comprising a rough- 55 ened, or corrugated base, and an upwardly projecting ange, or wall surrounding the same, the height of the Wall being substantially the height of the heel and having the front wall set rearward, or at an angleA less 6o than a right angie with relation to the bottom of the Creeper, to clasp the breast of the heel, substantially in the manner herein shown and described for the purpose set forth.

JOHN E. SCOTT.
